Easy, just don't pick any fights before level 10-20
I only play dead is dead and don't really die.. ever. So I usually just let Ralof tank everything in the starting cave, then let him escort me to riverwood, make a little money, help Faendal and take archery training 5 levels. Then follow the road to Whiterun, the few wolves on the road aren't much of a problem and then instead of going for the dragonstone I take the cart to Riften, run around the city, gather herbs etc. If I pull a spider or a bear, run to guards:P
Then join thieves guild, fail the first quest on purpose. Then usually make 2-3 invisibility potions or steal them, sneak into the guild and do the small jobs for gold + gather plants for potions and train archery and sneak every level. Oh and invest all into health till 400 or so. Around level 15 it's already a lot easier and level 30 I don't even have to try
Put then I usually died in the past because I got reckless, went out in nice clothes instead of those with good armor and sneak bonuses or was too lazy to make myself an invisibility potion or health potions for those tight spots. Oh and I fell to death a few times too:P
